US Patent 9961992 Height adjustable monitor and keyboard support

A height adjustable workstation for positioning a monitor and a keyboard relative to a work surface. The height adjustable workstation can include a stationary column positioned below the work surface and a movable column coupled to the stationary column and vertically extendable above the work surface.
